At present, there is automated workspace cleanup based on a free space threshold. This doesn't solve the case of forcing a mass cleanup when the workspace(s) for a job have corrupted state. Previously, an option to force a cleanup was provided on several jobs. However, this would only cleanup the workspace(s) in which the triggered build would be running and not all workspace(s) associated with that job. A mechanism is clearly need to allow either all workspace(s) for all jobs to be cleaned up as the "nuclear option" or to allow all of the workspace(s) for a signal job to be purged.
